Abstract: A system and a method include a port extender communicatively linked to a controlling bridge. Network data is received from a local network peer downstream to the port extender. Whether a destination of the network data is a recognized downstream network peer of the port extender is determined. The network data is selectively routed according to whether the destination of the network data is a recognized downstream network peer of the port extender.

Abstract: Disclosed are various embodiments for providing a data packet with timestamp information. A data packet is generated such that it comprises a payload and a header. The payload comprises a first timestamp field that comprises data indicating when a network device processed the data packet. The payload also comprises a body data field and a body data protocol field. The body data protocol field comprises data identifying a protocol used by body data in the body data field. The header comprises a payload protocol field that comprises data identifying that the payload comprises timestamp data.

Abstract: A network switch for network communications includes an embedded programmable state machine to monitor data flows through the switch. The programmable state machine is configured to retain selectable states of selectable data packet fields. Programmable switch logic operative with the programmable state machine is configured to output one or more potential actions to be taken based on a selectable computation of detected selectable states. The programmable state machine can be implemented with either table lookups or flexible logic.

Abstract: A system and method to monitor network congestion is provided. The system includes a plurality of ingress, egress ports, and a plurality of queues coupled to the ingress and egress ports and configured to store incoming and outgoing packets. The system also includes a monitoring unit configured to monitor at least one attribute of packets in at least one queue when a start condition occurs, stop monitoring the attribute when an end condition occurs, determine a flow that caused the start condition based on the monitored attribute, and report the monitored attribute and the flow.

Abstract: A technique in which at least one controlling bridge controls data traffic among devices located lower in hierarchy below the controlling bridge. Those devices include a plurality of porting devices, such as line modules and port extenders, which ultimately communicate with an end point device, referred to as a station. At least two physical pathways from a controlling bridge to a station are grouped together into a virtual trunk to provide multiple physical pathways for packet transfer when operating in a dual-homed mode.
